Release Notes for the Catalyst 3750, 3560, 2970, and
The stack master and the other Cisco EtherSwitch service modules or Catalyst 3750 switches in the stack are stack members.
The easiest fix I can think of would be to copy the IOS from the master switch, the slave switch.
Switches with different major version numbers are incompatible and cannot exist in the same switch stack.
In advance, you may not be connected, you can configure the stack member number, switch type, and the interfaces, with a switch that are currently part of the stack..
One of the Cisco EtherSwitch service modules or Catalyst 3750 switches controls the operation of the stack and as the stack master.
If it is a switch stack, its default stack member connects number changes to the lowest available member number in the stack.
If it is used by another member in the stack, the switch with the lowest available number in the stack.
I also reseating tried the stacking cable between 1-2 and 2-1, and even replace it with a brand new stacking cable completely, but the same switch stack-ports summary.
Each stack Element includes a standalone switch, retains its member number until you manually change the number or if the number is already in use by another member of the stack.
The switch added to the switch stack and that receives this configuration will change as the provided.

-NG. The stack members use the Cisco StackWise technology, behavior, and work together as a unified system. Example, if the switch 2, the 2 is. The interface associated with the provisioned switch does not appear in the display of the specific function, for example, it appears in the show vlan user EXEC command output. switch on, then turn off this switch after the master was turned on and the stacking cable has been applied. I plan on doing in production, so please let me know if I’m all of the steps are missing here, or I’m doing something wrong. and local laws of the country. Within the switch stack, the Catalyst 3750 switch or Cisco EtherSwitch service module is the stack master.. Switches with the same Cisco IOS software version as the stack master immediately in the switch stack to connect. The GigaStack GBIC negotiates automatically the duplex setting of each port to maximize the bandwidth for your configuration. Importers, exporters, distributors and users are responsible for compliance with U.S. If the number is of another member of the stack, the switch with the lowest available number in the stack selected. The master LED in the front panel of the 3750 switch lights up green when the switch is the master in the stack. Refer to Catalyst 3750 Software Upgrade to update in a Stack configuration with use of the command-line interface, the IOS in a catalyst 3750 switch. The startup configuration file ensures that the switch stack, store and use the stored information, whether or not the provisioned switch is part of the switch stack. The need to achieve was a computer in the LAN via a VPN connection managed by the LAN gateway (Cisco 1921). The software uses the automatic update (auto-update) and the automatic advise (auto-advise) features. Stack initialization, the nondefault interface configuration information in the startup configuration file for the provisioned interfaces (potentially of the wrong type)
I think, if you are in the ROMMON mode Pretty sure he doesn’t touch the stacking cable, it could a problem arise from turning off the master in the stack. If the stack master is not available, the stack members that remain at the election of a new stack master. — Quote from WebUser Adam Sibille. This is because the stack members that are powered on within the same 20-second time frame participate in the stack master election and have a chance to become the stack master. But these are written, system-environment-variables. At this point, most of the configuration is synchronized between the two switches (vlans, etherchannel, port, STP.). If you need commands such as copy on the switch stack don’t hesitate to ask. To view the stack Protocol version of your switch stack, you can use the output of the show platform stack-manager command.. I had to manually configure the switch ports. At times, switches with a lower software priority than the stack master, but all stack members participate in the stack master re-election
